Effectiveness of non-operative approaches in active enamel carious lesions: a retrospective longitudinal study.

The aim of the study was to investigate the effectiveness of non-invasive and micro-invasive treatments in active enamel carious lesions in high-caries-risk children. Clinical records of children treated in a dental school setting were retrospectively screened for active enamel carious lesions treated non-invasively (topical fluoride applications, oral hygiene instruction, or dietary guidance) or micro-invasively (sealant). The control of active carious lesions was set as the main outcome established by the combination of inactivation and non-progression of the lesions based on Nyvad and ICDAS criteria, respectively. Individual and clinical factors associated with the outcome were analyzed by Poisson regression. The sample consisted of 105 high-caries-risk children with a mean age of 8.3 (± 2.4) years. From a total of 365 active enamel carious lesions, most lesions (84.1%) were active non-cavitated carious lesions (ICDAS scores 1 and 2) and only 15.9% presented localized enamel breakdown (ICDAS score 3). Of these, 72.6% were inactivated and 92.1% did not progress (mean time of 6.5 ± 4.1 months). The prevalence of controlled carious lesions was higher among children older than 6 years (PR:1.43; 95%CI:1.00-2.03; p = 0.04) and in those with better biofilm control (PR:0.99; 95%CI: 0.98-0.99; p = 0.03). Non-operative approaches are effective for controlling active enamel carious lesions. The majority of active enamel carious lesions became inactive and did not progress after treatment. Caries control was associated with older children and better biofilm control.

Is there a better interceptive treatment for unerupted palatally displaced canines? A network meta-analysis.

This systematic review aimed to investigate if there is a better interceptive treatment for palatally displaced canines (PDC) in the mixed dentition stage. The PubMed/MEDLINE, CENTRAL, Scopus, and EMBASE databases were searched for randomized clinical trials related to the research topic. The gray literature and reference lists were also assessed. Network meta-analysis was conducted to analyze the effects of different approaches on PDC eruption. The surface under the cumulative ranking area was calculated to rank the treatments. The certainty of the evidence was evaluated using the GRADE approach. Of the 892 eligible studies, 18 were selected for full-text analysis and 9 for meta-analysis, involving 506 participants and 730 PDC, to compare 9 approaches. The proportion of erupted PDC was significantly higher for all interceptive treatments compared with control (no intervention). Furthermore, the proportion of erupted PDC was higher in patients subjected to rapid maxillary expansion (RME) than those who underwent double extraction of primary canine and primary molar (relative risk (RR) = 2.68 ICr95%: 1.12-9.35). A higher proportion of erupted PDC was found for RME (RR = 3.07 ICr95%: 1.31-10.67), RME plus use of transpalatal arch (TA) plus extraction of primary canine(s) (EC) (RR = 1.43 ICr95%: 1.09-1.95), EC plus use of cervical pull headgear (RR = 1.38 ICr95%: 1.11-1.79), and EC plus use of TA (RR = 1.36 ICr95%: 1.00-1.9) than for EC. RME was most likely to be considered as the best interceptive treatment. Overall, the certainty of the evidence was considered low due to imprecision and indirectness. In conclusion, no intervention in the mixed dentition stage is the worst choice for PDC.

A 12-month Follow-Up Study of Pulp Oxygen Saturation in Deciduous Molars After Selective and Nonselective Carious-Tissue Removal: A Randomized Pilot Trial

ABSTRACT Objective: To compare the pulp vitality of deciduous molars before and after selective caries removal (SCR) or nonselective caries removal to hard dentin (NSCR) over one year, using oxygen saturation percentage (%SaO2). Material and Methods: Deciduous molars with deep occlusal/proximal-occlusal caries lesions were randomized to SCR (n=22) or NSCR groups (n=22). After the caries removal, the teeth were protected with calcium hydroxide cement and restored with composite resin (Filtek Z250). The pulp condition diagnosis was evaluated at baseline, immediately after caries removal, and follow-up (7 days, 1-, 6- and 12-months) by %SaO2. Pulp exposure and pulp necrosis were primary outcomes, and %SaO2 was secondary. Results: Intraoperative pulp exposure occurred in four teeth of the NSCR group (18.2%) and one tooth of the SCR group (4.5%) (p>0.05). Two cases of pulp necrosis occurred in the NSCR group (10%). No difference in %SaO2 pulp was observed in the inter-and intragroup comparison over time (p>0.05). Conclusion: Advantageously, the %SaO2 minimizes preoperatory pulp vitality diagnosis subjectivity before SCR/ NSCR treatments. Furthermore, the pilot study results suggest the pulp response of deciduous molars, when evaluated by clinical, radiographic, and pulp %SaO2 seems not to differ between teeth treated with SCR or NSCR.

The Effectiveness of Lingual Frenectomy and Myofunctional Therapy for Children: A Randomized Controlled Clinical Trial.

Purpose: To evaluate the effectiveness of lingual frenectomy, as a standalone treatment or in association with myofunctional therapy, on the general and functional aspects of six- to 12-year-old children with anomalies in the lingual frenulum.
Methods: This randomized controlled clinical trial involved 40 children diagnosed with altered lingual frenulum. Children who received a frenectomy were evaluated 15 and 30 days after the procedure. After 15 days, the children were randomized into two groups: a group that received isotonic tongue exercises (Study Group [SG]) and a group that did not receive isotonic tongue exercises (Control Group [CG]). The outcome evaluator was blinded to group assignment. Statistical tests were used to compare between and within groups (P <0.05).
Results: There were 20 children in each group. SG children improved significantly when compared to CG subjects regarding tongue mobility (P =0.016), maximum mouth opening (MMO; P =0.024), and MMO with the tip of the tongue touching the incisive papilla (P =0.026).
Conclusion: Frenectomy associated with myofunctional therapy benefitted tongue mobility.

Aspectos anatômicos e funcionais da língua após frenectomia em gemelares: relato de casos clínicos / Anatomic and functional aspects of the tongue after frenectomy in twin: clinical cases report

Objetivo: Relatar dois casos clínicos de alteração de frênulo lingual em gemelares, com 10 anos de idade, ambas do sexo feminino, avaliadas nos aspectos anatômicos e funcionais da língua antes e 15 dias após a frenectomia. Relato de casos: Inicialmente, o odontopediatra realizou a anamnese com a mãe. Em seguida, as participantes foram submetidas à avaliação clínica odontológica e, posteriormente, foi realizada a avaliação fonoaudiológica do frênulo lingual. A avaliação fonoaudiológica foi realizada por meio do Protocolo de Avaliação do Frênulo da Língua, que foi aplicado antes e 15 dias após a frenectomia. As duas participantes apresentaram melhor desempenho em provas anatômicas após o procedimento cirúrgico. Entretanto, algumas alterações, principalmente ao elevar a língua, continuaram sendo observadas em uma das pacientes 15 dias após a frenectomia. Ademais, as duas participantes passaram a executar a maioria dos movimentos de língua com maior precisão. No que se refere à fala, somente a participante que apresentava um maior número de alterações fonéticas anteriores, permaneceu com algumas alterações na fala decorridos 15 dias da cirurgia. Discussão: Algumas dificuldades envolvendo mobilidade da língua e alterações na fala podem persistir após a realização da cirurgia, indicando a necessidade de intervenção fonoaudiológica específica. Conclusão: Ambos os casos apresentaram melhora no desempenho tanto nas provas anatômicas quanto funcionais após a frenectomia.

Aim: to report two clinical cases of alteration of the lingual frenulum in twins, aged 10 years, both female, evaluated in the anatomical and functional aspects of the tongue before and 15 days after the frenectomy. Case reports: Initially, the paediatric dentistry performed the anamnesis with the mother. Then, the participants were submitted to a dental clinical evaluation and, sub-sequently, the speech language pathologist evaluation of the lingual frenulum was performed. The speech language pathologist assessment was performed using the Tongue Frenulum Evaluation Protocol, which was applied before and 15 days after the frenectomy. Both participants performed better in anatomical tests after the surgical procedure. However, some changes, especially when elevating the tongue, continued to be observed in one of the patients 15 days after the frenectomy. In addition, the two participants started to perform most of the tongue movements with greater precision. About speech, only the participant who had a greater number of previous phonetic changes, remained with some speech disorders after 15 days of surgery. Discussion: Some di-fficulties involving mobility of the tongue and changes in speech may persist after surgery, indicating the need for specific speech therapy intervention. Conclusion:Both cases showed improvement in performance both in anatomical and functional tests after frenectomy

Reduction in erosive tooth wear using stannous fluoride-containing dentifrices: a meta-analysis.

Dentifrices containing different active agents may be helpful to allow rehardening and to increase the resistance of the eroded surface to further acids or mechanical impacts. This study aimed to compare the effects of conventional (sodium fluoride [NaF]) and stannous fluoride (SnF2)-containing dentifrices on reducing erosive tooth wear (ETW). The PubMed/MEDLINE, Scopus, LILACS, BBO, EMBASE, TRIP electronic databases, and grey literature were searched until January 2021 to retrieve relevant in vitro and in situ studies related to research question. There were no restrictions on publication year or language. Two authors independently selected the studies, extracted the data, and assessed the risk of bias. ETW data were pooled to calculate and compare both dentifrices (overall analysis) and in vitro and in situ studies separately (subgroup analysis). Statistical analyses were performed using RevMan5.3 with a random effects model. Of 820 potentially eligible studies, 101 were selected for full-text analysis, and 8 were included in the systematic review and meta-analysis. There was a significant difference between SnF2-containing dentifrices and NaF dentifrices only for in vitro studies (p=0.04), showing a higher effect of the SnF2-containing dentifrices against the erosion/abrasion (effect size: -6.80 95%CI: -13.42; -0.19). Most in vitro and in situ studies had high and low risk of bias, respectively. In vitro literature suggests that the ETW reduction is greater when using SnF2-containing dentifrices instead NaF-containing dentifrices. However, the evidence level is insufficient for definitive conclusions. Clinical trials are necessary for a better understanding of the effect of these compounds on ETW.

Pulp Vitality and Longevity of Adhesive Restorations Are Not Affected by Selective Carious Removal: A Multicenter Clinical Trial.

The aim of this multicenter randomized clinical trial was to evaluate the pulp vitality and survival rate of adhesive restorations performed on posterior deciduous teeth after non-selective (NSCR) or selective (SCR) carious tissue removal over 33 months. One hundred and seven children (average age 4-8 years, SD 1.4) with at least two active moderate cavitated lesions in dentin were included. Teeth were randomized and submitted to NSCR or SCR before composite resin restoration. Restorations were clinically and radiographically assessed at baseline, 6, 12, 18, 24, and 33 months by a blinded, trained, and calibrated operator in each center. The characteristics of the restorations were recorded according to FDI criteria and were considered as restorative failures when scores 4 or 5 were presented. Pulp vitality was measured by clinical and radiographic examinations, and those teeth that presented any signs or symptoms of irreversible pulpitis or pulp necrosis were considered as failure. Data were analyzed by a Cox regression model with shared frailty, considering two outcomes: pulp and restorative. A total of 278 restorations (137 after NSCR and 141 after SCR) were performed at baseline in four different centers and there was no loss in the follow-up period. Survival rate was 97.1 and 87.1% for pulp and for restorative outcome, respectively. The overall annual failure rate was 7%. There were no differences in the failure risk according to the treatment group, center, and all the clinical and demographic variables, regardless of outcome. Composite restorations of active moderate deep carious lesions performed on posterior primary teeth show satisfactory survival for restorative and pulp outcome after a 33-month follow-up, regardless of the technique executed for carious tissue removal.

Erosive Tooth Wear and Erosive Esophagitis in Children: An Observational Study in Porto Alegre, Brazil.

The aim of this study was to establish and compare the prevalence and severity of erosive tooth wear (ETW) in children with and without erosive esophagitis. Children aged 5-12 years, scheduled for upper digestive endoscopy at the Pediatric Gastroenterology Service of the Children's Hospital Santo Antonio, Porto Alegre, Brazil, were eligible to participate in this study. Patients who presented erosive esophagitis at endoscopy were defined as gastroesophageal reflux disease (GERD) carriers, and the severity was described according to the Los Angeles classification. The oral cavity examination was performed by a trained and calibrated dentist and ETW was classified using the Basic Erosive Wear Examination (BEWE) index. Parents/guardians answered a questionnaire about the patients' diets and frequency of consumption of acidic foods and beverages. A total of 110 children were included in the study. Erosive esophagitis was observed in 24 patients (21.8%) and all of them (100%) presented ETW, showing a statistically significant association between these 2 conditions (p < 0.05). Among children who did not present with erosive esophagitis (n = 86), 54 (64.3%) had an ETW risk level of none according to their BEWE scores (0-2). The results of this study showed a statistically significant association between erosive esophagitis and ETW, thus it can be concluded that it is important to recognize groups at risk of ETW and act together with medical professionals to ensure adequate oral health for these patients.

Repair increases the survival of failed primary teeth restorations in high-caries risk children: a university-based retrospective study.

OBJECTIVES: We investigated factors associated with failure of adhesive restorations in primary teeth and whether repair may increase the survival of failed restorations placed in high-caries risk children. MATERIALS AND METHODS: The sample comprised children who attended a university dental service to perform restorative treatment in primary teeth. Data were collected retrospectively from clinical records to assess the longevity of restorations. The outcomes were calculated in two levels: "Success" (Level 1)-when any re-intervention was considered as failure; "Survival" (Level 2)-when repaired restorations were considered clinically acceptable. The Kaplan-Meier survival test was used to analyze the longevity of restorations. Multivariate Cox regression with shared frailty was used to assess factors associated with failures (p < 0.05). RESULTS: A total of 584 primary teeth restorations (178 patients) were included in the analysis. The longevity of restorations up to 36 months (Level 1) was 34.8% (AFR 29.6%). Multi-surface restorations showed significantly more failures than single-surface ones (HR 1.69; 95% CI 1.18, 2.41), and endodontically treated teeth presented more failures compared to vital teeth (HR 2.22; 95% CI 1.35, 3.65). There was an increase in restoration survival when repair was not considered as failure (p < 0.001). The survival of repaired restorations (Level 2) reached 43.7% (AFR 24.1%). CONCLUSIONS: Adhesive restorations placed in primary teeth of high-caries risk children showed restricted longevity; however, the repair of failed restorations has increased its survival over time. CLINICAL RELEVANCE: Repair is a more conservative and technically simple procedure that increases the survival of failed restorations in primary teeth.

Maternal characteristics, home environment, and other factors associated with traumatic dental injuries in preschool children.

BACKGROUND/AIMS: The importance of external factors such as maternal and home characteristics on traumatic dental injuries needs to be investigated. The aim of this study was to evaluate the association between maternal and home characteristics and dental trauma in preschool children. MATERIAL AND METHODS: This cross-sectional study using a cluster random sample evaluated children between 3 and 4 years of age from Porto Alegre, Brazil. Mothers completed the Brazilian version of the Beck Depression and Anxiety Inventories (BDI and BAI). They answered questions about sociodemographics, maternal behaviors, and home characteristics. Dental trauma was assessed by the Children's Dental Health Survey criteria. Malocclusion and deleterious habits were also assessed. The multinomial logistic regression model was used to investigate the association of exploratory variables with different categories of dental trauma. Odds ratios (OR) and 95% confidence intervals were calculated. RESULTS: A total of 163 pairs of children and mothers agreed to participate (78.4% response rate). The prevalence of dental trauma was 49.8%. Mother's work outside the home, overjet, and anterior crossbite were associated with the occurrence of enamel trauma, while having a younger mother, families having more siblings, and having a mother with university education were associated with increased odds of dentin/pulp trauma. CONCLUSION: Depression and anxiety in the mothers were not associated with dental trauma, while malocclusion characteristics were more relevant for less severe, enamel trauma. Socioeconomic and home environment characteristics played a role in more severe, dentin/pulp trauma.

The Role of Mother's Knowledge, Attitudes, Practices in Dental Caries on Vulnerably Preschool Children

Abstract Objective: To analyze the association between Early Childhood Caries (ECC) and mother´s knowledge, attitudes, and practices (KAP). Material and Methods: This cross-sectional study included a random sample of 163 preschool children aged 3-4 old in southern Brazil. The severity of dental caries and ECC was assessed by ICDAS criteria, while mothers completed the semi-structured questionnaire (KAP-ECC). Maternal behavior characteristics and answered questions about socioeconomic and demographic variables. Logistic regression was performed to evaluate the association of exploratory variables with ECC. For this approach, we calculated the odds ratio (OR) and 95% confidence intervals (95% IC). Results: Dental examinations revealed that 91.4% of children presented ECC (ICDAS = 3, 4, 5 or 6). Among those children, 31.9% presented cavities (ICDAS ≥ 3). Family income was significantly associated with the presence of ECC (OR 2.17; 95% CI: 1.41-3.36). Regarding KAP-ECC, mothers have knowledge related to ECC etiology, reported dental hygiene attitudes and practices that can prevent ECC but reported less healthy attitudes and practices regarding child's diet, specifically with respect to bottle and breastfeeding habits (OR 0.52; 95% CI: 0.33-0.81). Conclusion: ECC was more frequent in children from low-income families and whose mothers reported the belief that milk with chocolate does not contribute to caries and that disagreed that it is normal that a 2-year-old baby wakes up during the night to suckle. That is, good knowledge toward health habits may impact on lower occurrence of ECC; however, this condition also depends on the socioeconomic level.

Impact of Early Childhood Caries and Maternal Behaviors on Oral Health-Related Quality of Life of Children

Abstract Objective: To evaluate the impact of early childhood caries, maternal behaviors and associated factors on the oral health-related quality of life (OHRQoL) of preschool children. Material and Methods: This cross-sectional study was conducted with 163 preschool children aged 3-4 old from Porto Alegre, Southern Brazil. Mothers completed the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS) and answered questions about sociodemographic and maternal behaviors characteristics. The severity of dental caries was assessed by ICDAS criteria for evaluated early childhood caries (ECC). A Poisson regression model was used to investigate the association of ECC and associated factors on OHRQoL. Results: A total of 91.4% of preschooler children was ECC (ICDAS ≥ 1). Mean ECOHIS function domain and parental anxiety domain scores were significantly higher in children with dental caries (p<0.05). The adjusted Poisson regression model showed that household income, maternal education, mother's job status and breastfeeding time was significantly associated with ECOHIS scores. Regarding oral conditions, child caries experience was associated with worsening child and family quality of life (RR 2.21; 95% IC: 1.43-3.41). Conclusion: Our findings suggest that ECC, socioeconomic and maternal behaviors characteristics influence children's OHRQoL.

Does selective carious tissue removal of soft dentin increase the restorative failure risk in primary teeth?: Systematic review and meta-analysis.

BACKGROUND: The authors conducted a systematic review of randomized controlled trials comparing the risk of experiencing restoration failure in primary teeth after complete and selective carious tissue removal of soft dentin. METHODS: The authors searched electronic databases (PubMed [MEDLINE], Scopus, Cochrane Central Register of Controlled Trials) and the ClinicalTrials.gov Web site with manual searching and cross-referencing for trials reporting restoration failure after follow-up of 6 months or longer. Two reviewers independently selected studies, extracted data, and assessed the risk of bias and quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation approach. The authors performed intention-to-treat and per-protocol meta-analyses and calculated odds ratios (OR) as effect estimates in the random-effects model. RESULTS: From 327 potentially eligible studies, the authors selected 23 for full-text screening and included 4. Results showed increased risk of experiencing restoration failure (intention-to-treat analysis, OR [95% confidence interval] 1.74 [1.01 to 3.00], and per-protocol analysis, OR [95% confidence interval] 1.79 [1.04 to 3.09]) after selective carious tissue removal of soft dentin. The risk of bias was high, and the quality of evidence was low. CONCLUSIONS: Selective carious tissue removal of soft dentin may increase the risk of experiencing restoration failure in primary teeth. However, the evidence level is insufficient for definitive conclusions. PRACTICAL IMPLICATIONS: Patients with restorations performed after selective carious tissue removal of soft dentin should have shorter recall visit intervals to evaluate the restorations' quality and control caries disease, allowing for more conservative approaches, such as repair, in cases of defective restorations.

Prevalence of defective restorations and factors associated with re-intervention in primary teeth: A retrospective university-based study.

AIM: This retrospective study investigated the prevalence of defective restorations in a public dental service and factors associated with re-intervention in primary teeth. DESIGN: The sample consisted of all clinical records (census) of children presenting restorations in primary teeth, who had undergone dental treatment in a public set during 1-year period. For analysis, only restorations presenting defects related to esthetic, functional, or biological reasons at first clinical examination were included. The outcome 'Success' was set when the restoration received no treatment (monitored), refurbishing, sealing of margins, or was repaired. Otherwise, 'Failure' was set whenever the restoration was either replaced or if another treatment affecting the restoration was necessary (endodontic treatment or tooth extraction). Poisson regression model was used to assess the prevalence of patient- and tooth-related factors that may influence the re-intervention decision (repair or replacement). RESULTS: From a total of 302 restorations placed in 114 children, 37.7% presented some type of defect. Restorations with recurrent caries were more frequently present in caries-active patients (P = 0.03) and were frequently replaced (95% CI, 1.05-3.22, RR = 1.84, P = 0.03). CONCLUSION: Presence of recurrent caries influences the re-intervention decision, leading to restoration replacement in most cases.

Patient- and treatment-related factors may influence the longevity of primary teeth restorations in high caries-risk children: A university-based retrospective study.

PURPOSE: To evaluate the longevity and factors associated with failure of primary teeth restorations placed in high caries-risk children. METHODS: The sample was comprised of children treated in a University Dental Service. Patients' records were screened retrospectively to determine whether they had received restorative treatment in primary teeth presenting cavitated caries lesions. Kaplan-Meier estimator and Multivariate Cox regression analysis with shared frailty were used to assess restorations' survival and factors associated with failure, respectively. RESULTS: 123 high caries-risk children (10.3±4 DMF-T) with 316 restorations were analyzed. The 3-year survival reached 53.4% (AFR=18.8%). Restorations placed without rubber dam (P= 0.04), over selective caries removal (P= 0.03), with calcium hydroxide liner (P< 0.01) and glass-ionomer cement (P= 0.04) presented lower survival rates. Caries-controlled patients presented significantly (P= 0.03) higher rates of restoration survival (77.7%) than caries-active patients (49.9%). The adjusted model showed that restorations placed in teeth after selective caries removal showed 3.41 times higher risk of failure compared with restorations over complete caries removal (95%CI:1.37-8.46). CLINICAL SIGNIFICANCE: Adhesive restorations placed in high-caries experience patients have limited survival rates. Some treatment-related factors may influence the performance of these restorations. A strict preventive regimen to control dental caries activity must be followed in order to increase the restoration survival.

Caries progression as a risk factor for increase in the negative impact on OHRQOL-a longitudinal study.

OBJECTIVES: The aim of this study is to evaluate the association between caries lesions progression and oral health-related quality of life (OHRQoL) among Brazilian preschools, after 2 years. MATERIALS AND METHODS: At baseline, 163 children (3-4 years old) enrolled in 12 public primary care services in Porto Alegre/RS-Brazil were evaluated. After 2 years, 119 children were re-evaluated. Calibrated examiners employing the ICDAS criteria conducted clinical examinations. A socio-demographic questionnaire and the Brazilian version of the Early Childhood Oral Health Impact Scale were applied to the parents of the children at baseline and 2-year follow-up. Data analysis was performed using a hierarchical approach based in a conceptual framework testing by Poisson regression. RESULTS: The number of surfaces that progressed from baseline to 2-year follow-up was associated with an increased negative impact on OHRQoL. CONCLUSIONS: Caries progression increased the negative impact on OHRQoL. CLINICAL RELEVANCE: The progression of caries lesions could negative impact on OHRQoL in Brazilian preschoolers.
